GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 500,? 38, dated July 4, 1893.

Application filed December 26, 1888. Serial No, 294,607. (No model.)

To wZZ whom it may concern:

Be it known that I, CHARLES COLAHAN, a citizen of the United States, residing at Cleveland, county of Ouyahoga,and State of Ohio, have invented certain new and useful Im provements in Grain-Binders, of which the following is a specification, reference being had to the accompanying drawings.

Myinvention relates tothe mannerof clutching and unclutching the binder by means of the binder arm shaft on which the binder arm and its crank are loosely journaled and controlled by devices that admit a slight additional rotary movement of said shaft in either direction to facilitate the operation of the clutching devices in connection with its normalfunction of actuating the binder and compressor arm Without materially changing the construction or interfering with its normal action in eitheroffice.

Figure 1 is a view of the binder drive Wheel, the binder arm pitman, and crank, with the binder at rest as it is unclutched during the formation of the bundle. Figs. 2 and 3 are detail views of the detached portions of the binder. Fig. 4 is a detail view of aportion of the same as the binder is clutched and started in operation. Fig. 5 is'a detail view of the compressor andtripping arm and the supporting plate secured to the shaft, in their normal positions during the formation of the bundle. Fig. 6 is a view of the same as closed during the binding of a bundle. Fig. 7 is a view of the plate that is keyed to the binder arm shaft and its laterally projecting lugs that control the movements of the binder arm.

In the drawings like letters refer to like parts.

E is the binder arm; K its shaft; F the compressor and tripping arm that is pivoted to the heel of the binder arm in the usual manner and may be constructed in one piece as it is rigid throughout its length.

0 is the plate or yoke that is keyed to the binder arm shaft and it is provided with controlling lugs or stops 0 0 0".

M is the spring supporting the compressor and tripping arm. 1

D is the crank arm mounted to rotate within certain limits on the binder arm shaft.

arm D that alternately engage the central lug Z secured in the binder arm shaft.

B is the crank arm locking latch and is pivoted on the crank arm. S is its retaining spring also secured to the crank arm and causes the engagement of the locking latch with the central luglin the binder arm shaft, thereby locking said crank arm during the formation of the bundle.

O is the clutch tripping finger keyed to the binder arm shaft; J the clutching pawl pivoted to its supporting arm which is keyed on the continuously running packer shaft J. This clutching device is shown in a former patent granted to meApril 14, 1885, No. 315,479.

G is the binder arm actuating pitman which is of the usual well known form.

H is a tripping lug secured to the pitman G and is adapted to bear against the latch B to trip. or unlock it from engagement with the central lug in the binder arm shaft while the binder arm is retracted to open the receptacle for the incoming grain. As shown in Fig. 3the action of the pitman Gforces the crank D downwardly and at the same time the looking latch B is tripped from its engagement with the central lug Z of the binder arm shaft to permit said shaft and other parts connected therewith to be rocked sufiiciently to throw the clutch tripping arm out of engagement with the pawl of the binder clutch as the binder is unclutched from engagement with the continuously running shaft J.

The binder and its clutching mechanism to which my devices are applied being of the usual Appleby type, I have only illustrated such parts as are deemed necessary to fully show my invention.

In the operation, the grain accumulates in the receptacle from the harvester and is packed against the bundle forming portion of the compressing and tripping bar F, that rests on the lug 0' of the plate 0 at a point near its pivot to the binder arm. Said plate being keyed to the shaft K, the pressure of the grain causes the same to move downwardly against the lug 0' and thereby produce a slight rotation of the shaft K, and a predetermined bulk of grain will rotate the shaft sufficiently to cause the clutch tripping finger O, that is moved thereby, to rise from con= tact with the clutch pawl and admit the clutching and starting of the binder, and as the pitman G is caused to move upward in the usual manner the crank arm D as it rises brings its lug Z in contact with the central lug Z secured to the shaft K, and causes the shaft to rotate. At the same time the locking latch B that is pivoted to the crank arm is released from contact with the lug H on the pitman G and the spring S causes the latch to rock on its pivot and its upper point Will engage with the central lug Zthat is keyed to the binder arm shaft thereby locking the crank arm to its shaft, and its plate 0 and lug 0 that controls the binder arm will cause the binder arm to rise and act with the compressor in formation of the bundle in the usual manner, and the reverse movement of the plate 0 and its lug 0 will force the binder arm back and thereby carry the compressing and tripping arm to their normal position in the receptacle as the pitman Gwill cause the crank arm D to move downward and the latch B being in contact with the central lug Z, as shown in Fig. 4, is caused to unlock the same as the lug H is brought in contact therewith as shown in Fig. 8 which thus leaves the shaft K free to be operated in its function of unclutching the binder without moving the binder arm crank D or its pitman G.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The binder arm shaft K the clutch tripping finger O and plate 0 and its stops rigidly secured on said shaft, the binder arm E and its crank D both loosely journaled on said shaft, and in certain limits admitting the partial rotation of the shaft, combined with the pitman G pivoted to and retaining said crank D in a fixed position until the binder arm shaft may be caused to rotate and move said clutch tripping finger C to admit the unclutching and starting of the binder substantially as shown and described.

2. The shaft K with the binder arm E journaled thereon, the compressor and tripping finger F pivoted to said arm, its elastic supporting spring M, plate O,having supporting lugs 0 and o secured to said shaft combined with the clutch tripping finger O and the clutching pawl J and its supporting arm pivoted on the continuously running shaft J operating to clutch andunclutch the binder substantially as set forth.

3. The shaft K, the binder arm E loosely journaled thereon, its supporting lug 0 on plate 0, the compressor and tripping arm F pivoted to said binder arm, combined with the plate 0 having a supporting lug 0 and secured to said shaft K and its clutching finger O secured to the binding arm shaft to admit of the unclutching and starting of the binder substantially as shown and described.

4-. The binder arm shaft K, the clutch tripping finger O rigid on said shaft the lug Z on said shaft combined with the crank arm D loosely j ournaled on said shaft, the projections on the hub of said crank adjusted to be engaged by the lug on the shaft the locking latch B mounted on the crank armD and the pitman G having the lug H adapted to engage the latch B all operating substantially as and for the purposes shown and described.

5. The combination of a binder arm shaft and the clutch tripping finger secured thereon, with the rigid pitman and its crank arm flexibly secured to said shaft, to admit a slight rotation of said shaft and its clutch finger for the purpose of clutching the binder without disturbing the relation of the pitman and its crank during the accumulation of grain for the formation of the bundle.

6. The combination of the pitman G and its crank arm flexibly secured to the binder arm shaft, and provided with a locking latch to secure to said shaft the crank and pitman during the opening and closingof the binder arm, and the tripping lug on said pitman for unlocking said latch when the binder is unclutched to admit the tripping action of said binder arm shaft and its clutch finger substantially as shown and described.
